You should get the amount of sleep you need before you drive anywhere.
That’s the message from the AAA Motor Club.
According to a spokesperson for the AAA, “Thirty-five percent of U.S. drivers sleep less than the recommended 7 hours daily, and with drowsy driving involved in one in five fatal crashes each year, this is something we really have to pay a lot of attention to.”
“You cannot miss sleep and still expect to be able to safely function behind the wheel,” said Dr. David Yang, executive director for the AAA Foundation for Traffic Safety. “Our new research shows that a driver who has slept for less than five hours has a crash risk comparable to someone driving drunk.”
The AAA Foundation for Traffic Safety’s report, Acute Sleep Deprivation and Risk of Motor Vehicle Crash Involvement, says drivers missing 2-3 hours of sleep in a 24-hour period more than quadrupled their risk of a crash compared to drivers getting the recommended seven hours of sleep. This is the same crash risk the National Highway Traffic Safety Administration associates with driving over the legal limit for alcohol.
The AAA Foundation report found that in a 24-hour period, crash risk for sleep-deprived drivers increased steadily when compared to drivers who slept the recommended seven hours or more:
- Six to seven hours of sleep: 1.3 times the crash risk
- Five to six hours of sleep: 1.9 times the crash risk
- Four to five hours of sleep: 4.3 times the crash risk
- Less than four hours of sleep: 11.5 times the crash risk
Symptoms of drowsy driving can include having trouble keeping eyes open, drifting from lanes or not remembering the last few miles driven. However, more than half of drivers involved in fatigue-related crashes experienced no symptoms before falling asleep behind the wheel. AAA urges drivers to not rely on their bodies to provide warning signs of fatigue and should instead prioritize getting plenty of sleep (at least seven hours) in their daily schedules. For longer trips, drivers should also:
- Travel at times when normally awake
- Schedule a break every two hours or every 100 miles
- Avoid heavy foods
- Travel with an alert passenger and take turns driving
- Avoid medications that cause drowsiness or other impairment
